This procedure covers removal and replacement of the side airbag module located in the front seat back on a 2011-2014 Ford F-150, including proper disconnection of the supplemental restraint system (SRS).
Warnings
⚠️SAFETY-CRITICAL: This procedure involves the supplemental restraint system (SRS). Improper service can cause airbag deployment resulting in severe injury or death. If you are not confident in your ability to perform this work, seek professional service immediately.
⚠️The battery MUST be disconnected and the system MUST be allowed to discharge for at least 2 minutes before beginning work. Failure to do so may result in airbag deployment.
⚠️Never probe airbag connectors with test equipment while connected. Always disconnect SRS components before testing.
⚠️Handle airbag modules with extreme care. Always place airbag modules on a secure surface with the trim cover facing UP, never face down. Store away from heat, electrical sources, and grease.
⚠Do not strike or jar the airbag module during removal or installation. Physical shock can cause deployment or render the airbag inoperative.
⚠Use only OEM Ford replacement airbag modules. Aftermarket parts may not deploy correctly and can cause serious injury.
⚠After installation, the SRS system MUST be scanned and any diagnostic trouble codes (DTCs) cleared using a professional scan tool. The airbag warning light must be verified OFF before returning vehicle to service.
ℹ️This procedure assumes front driver or passenger seat side airbag replacement. Side curtain airbags require a different procedure.

- Move seat fully forward or rearward depending on access requirements for the specific seat design
- Take photographs of connector routing and seat trim panel positions before disassembly for reference during reassembly
Procedure
- 1Remove seat from vehicleLocate the four seat mounting bolts at the base of the seat tracks (two front, two rear). Using an 18mm socket, remove all four seat mounting bolts. Tilt seat backward carefully and disconnect any electrical connectors at the seat base (seat heater, power seat controls if equipped) by pressing release tabs. With assistance, carefully lift seat assembly out of vehicle and place on a clean, padded work surface. Do not drag seat across interior surfaces.⚠Seat assemblies are heavy (40-60 lbs). Use proper lifting technique or get assistance to avoid injury or damage to interior trim.Torque specMounting Bolts34 Nm (25 lb-ft)
- 2Remove seat back trim panelWith seat on work surface, locate the trim panel fasteners on the rear of the seat back. Remove plastic trim clips or Torx screws (typically T20 or T30) securing the rear seat back trim panel. Carefully pry the trim panel away from the seat frame using trim removal tools, working around the perimeter. Note the location of any retaining clips for reinstallation. Set trim panel aside in a safe location with clips preserved.
- 3Locate and access side airbag moduleWith the rear trim panel removed, locate the side airbag module mounted within the outboard side bolster of the seat back frame. The module is typically a rectangular metal canister with a fabric deployment chute facing the seat upholstery. Identify the yellow SRS electrical connector attached to the airbag module and the mounting bolts (typically two Torx bolts).
- 4Disconnect airbag module electrical connectorCarefully access the yellow SRS connector. Verify battery has been disconnected for at least 2 minutes. Locate the connector locking mechanism (typically a sliding lock or rotating tab colored red or orange). Release the lock mechanism according to the connector design. Gently pull the connector halves apart using steady, straight pressure - do NOT twist or bend. Inspect connector pins for damage or corrosion. If pins are damaged, the entire wiring harness may need replacement - do not attempt repair.⚠️Verify battery has been disconnected for minimum 2 minutes before touching any SRS connectors. Never connect or disconnect SRS components with battery connected.
- 5Remove side airbag module mounting boltsUsing the appropriate Torx driver (typically T30 or T40), remove the side airbag module mounting bolts. There are typically two bolts securing the module to the seat frame. Support the airbag module with one hand while removing the second bolt to prevent it from falling. Keep track of any washers or spacers on the mounting bolts.Torque specSide Airbag Module Bolts7 Nm (5 lb-ft)
- 6Remove airbag module from seat frameCarefully lift the airbag module away from the seat frame, guiding the deployment chute and any remaining wiring through the seat structure. Handle the module gently - do not drop, strike, or place excessive pressure on it. Immediately place the removed airbag module on a secure, clean surface with the TRIM COVER FACING UP. Never place an airbag module face down. Store in a cool, dry location away from electrical sources, heat, moisture, and contaminants until disposal or reinstallation.⚠️Always place airbag modules trim cover facing UP on a secure surface. Never store face down - this can cause serious injury if unexpected deployment occurs.
- 7Inspect seat frame and wiring harnessWith the old airbag removed, inspect the seat frame mounting points for cracks, damage, or bent brackets. Verify mounting bolt threads are clean and undamaged. Inspect the yellow SRS wiring harness for chafing, cuts, pinching, or connector damage. Check that wire routing clips and grommets are intact. Any damage to the seat frame or wiring harness must be repaired before installing new airbag module. Verify the new airbag module part number matches the vehicle application and seat position (driver vs passenger).
- 8Position new airbag module in seat frameRemove new airbag module from packaging carefully. Verify it is the correct module for the vehicle and seat position. Position the new airbag module into the seat frame mounting location, aligning the deployment chute with the seat upholstery perforation or deployment path. Ensure no wiring is pinched or trapped. Align mounting bolt holes with the seat frame threaded inserts. The module should sit flush against the mounting surface.
- 9Install and torque airbag module mounting boltsInsert the side airbag module mounting bolts (with any original washers or spacers) and hand-thread them into the seat frame. Using a torque wrench and appropriate Torx bit, torque the bolts to exactly 7.0 Nm (5.0 lb-ft) in a cross pattern if two bolts are used. Do not over-torque - these are critical fasteners and excessive torque can damage the module housing or deployment mechanism. Verify module is securely mounted with no movement.⚠CRITICAL torque specification: Side airbag module bolts must be torqued to exactly 7.0 Nm (5.0 lb-ft). Over-torque can prevent proper deployment. Under-torque can allow module movement during deployment.Torque specSide Airbag Module Bolts7 Nm (5 lb-ft)
- 10Reconnect airbag electrical connectorRoute the yellow SRS connector back to the airbag module connector, ensuring the wire path follows the original routing and is not pinched, kinked, or under tension. Align the connector halves and press them together firmly until you hear or feel a positive click. Engage the connector locking mechanism (slide lock or rotate tab) to the locked position. Gently tug on the connector to verify it is fully seated and locked - it should not pull apart.
- 11Reinstall seat back trim panelPosition the seat back trim panel onto the seat frame, aligning all retaining clips with their corresponding holes. Press firmly around the perimeter to engage all clips. Install any Torx screws removed earlier and tighten securely but do not over-torque plastic fasteners. Verify trim panel is flush and secure with no gaps or loose areas. Ensure no wiring is visible or pinched between trim panel and seat frame.
- 12Reinstall seat assembly in vehicleWith assistance, carefully lift the seat assembly and position it over the four mounting points in the vehicle floor. Reconnect any electrical connectors at the seat base (heated seat, power seat controls) before lowering seat completely. Align all four seat mounting bolt holes with the floor threaded inserts. Insert all four seat mounting bolts and hand-thread them. Using an 18mm socket and torque wrench, torque all four seat mounting bolts to 61.0 Nm (45.0 lb-ft) in a cross pattern (front left, rear right, front right, rear left).⚠Seat mounting bolts are safety-critical. Must be torqued to exactly 61.0 Nm (45.0 lb-ft) to ensure seat remains secure in a collision.Torque specMounting Bolts34 Nm (25 lb-ft)
- 13Reconnect battery and clear SRS codesReconnect positive battery terminal first, then negative battery terminal using 10mm socket. Tighten terminals securely. Using a professional SRS-capable diagnostic scan tool, connect to the vehicle OBD-II port. Turn ignition to ON position (do not start engine). Access the SRS/airbag system and read any diagnostic trouble codes (DTCs). Clear all airbag-related codes. Turn ignition OFF, wait 10 seconds, then turn ignition back to ON. Verify the airbag warning light illuminates for 6-7 seconds during bulb check, then turns OFF. If light remains illuminated or flashes, there is a fault - do NOT drive vehicle until fault is diagnosed and corrected.⚠️If the airbag warning light remains ON or flashes after code clearing, there is a system fault. Vehicle is NOT safe to drive. Seek professional diagnosis immediately.
